2002 Chevy Tahoe Front End Noise

Rhall77, thanks for the reply. The tires are not cupped. Just for kicks, I swapped tires with my friends Tahoe and it still had the same noise. I even replaced my front wheel bearing hub assembly and the noise is still there. I can turn left or right and the noise is still consistent. Once I go past 35mph, the humming sound seems to go faster. It actually sounds like a small airplane but not as loud. When I start to slow down the noise slow down. Other than the noise, my Tahoe drives like it's brand new. I have stock tires on there. No big tread. If I drive below 35mph, it's fine. Maybe my fan?

I don't think I have a front diff. Because it's only a 2wd, unless i'm mistaken. When I jacked up the front end, I noticed when I spun my passenger side wheel by hand, I noticed a slight rattle coming from my wheel bearing. I replaced the driver side wheel bearing because it was making the same rattle and replaced it. The noise seems to still be coming from the driver side. Could a u joint be going bad and cause a sound coming from the front? I had a u joint go out on me before but on a different vehicle and you could tell where the noise was coming from. I did put my ears on the steering wheel while driving and noticed the sound was coming through the steering. Could it be that the sound is just resonating through out the chassis?

Ok I got it figured out. It was the passenger side front wheel bearing. I guess both my front wheel bearing was out. The weird thing was that all the noise was coming from the driver side wheel. No noise was coming from the passenger side. So I never really checked it. I guess I should of really checked it. When I grabbed the top and bottom of the tire and tried to rock it the first time, it didn't do anything but when I recently checked it again, it was barely rocking. So I replaced the passenger side wheel bearing hub assembly. And sure enough it was the passenger side. Now there's no more noise.
